wsgi example doesn't work for me: KeyError: 'paste.registry'

[Aaron Watters]

Hi folks.

I'd love to create WHIFF support for Tosca Widgets,
but I can't even get the example wsgi_app.py to work.

Traceback below. (I tried to add an issue to the Trac inteface,
posting here too just in case...)

Please help! Thanks! -- Aaron Watters

=== here is the traceback:

Please don't do that unless it has been confirmed that it *is* a bug.

And it isn't. You need to add a RegistryManager to your
application-stack. Which you can do by passing

stack_registry=True

to the make_middleware call.

I missed the documentation on the registry thing.
If if isn't documented, it's at least a documentation
bug imho. Thanks!

Here is the patch to your example application
which works after adding the keyword argument
like you said.
